This invention (relates to improvements in roofing structures. p

The primary object of this invention is the provision of an improved joint construotionfor flexible sheet roofing which will enable the 'utie lization of pre-fabricated material; which can be applied quickly and expertly by unskilled labor, and which is inexpensive and produces a neat and trim appearance.

A further object of this invention is the provision of 'an improved batten cover for sheet roofing which may be applied with facility and which is water-proof and will prevent the seepage of water beneath the sheet roofing thru capillary attraction.

' A further object of this invention is the provision of a, ventilated joint connection for sheet roofing materials which will enable the circulation of air; prevent water from entering'the same by means of capillary attraction, and one which will prevent condensationof moisture therealong.

Other objects and advantages of this invention will be apparent during the course of the following detailed description; r

In the accompanying drawingforming a part of this'specification, and wherein similar reference characters designate corresponding parts thruout the several views V I 'Figure l is a cross sectional view taken thru the improved batten cover or joint for sheet roofing material.

Figure 2 is a fragmentary showing in side elevation of a portion of the improved joint or cap and its associated construction.

In the drawing, whereinfor the purpose of illustration is shown only a preferred embodiment of the invention, the letter A may generally designate the improved joint structure. The sheathing B may be of wood, composition material or even steel decking. It is adapted to be covered by means of roll type roofing sheets C; which are usually twenty inches wide. This sheet material may be metal, asphalt, paper,

Congoleum, other compositionmaterial, fabric (such as canvas), tin or any other material desired.

The'upstanding wings or portions ID of adjacent roofing sheets C are adapted to be positioned against the sides of the batten D, which serves to construct the joint at the longitudinal meeting edges of the roofing sheets C.

Referring to the improved joint construction A, I prefer to provide anchor cleats l5, preferably of metal in capped relation upon the batten D.'- These'anchor cleats T5 are preferably of 3": length and they are relatively spaced about' 1! apart longitudinally'of the batten; Each of the same includes a top wall it which fits over the top of the batten D. Downwardly extending relatively divergent walls or side portions 11 and H! are extended from theopposite edges of the. top wall I6 of the cleat l5. These sidewalls or wings H and I8 terminate at their lower ends above the roofing material C andpresent-1m. turned wings or securing flanges 22 and '23, the edges of which bear against the inturned por tions IE3 of the roofing sheets C and press said material forming the portions lfl'tightly against the opposite sides of the batten D, "as shown in Figure 1 of the drawing. Nails E anchor thecleats l5 in place; the heads of the nails lying on top ofthe top walls 16, and the nails, of

course, extending thru the battens and into the sheathing B of the roof, as shown in Figure l of the drawing. If steel decking is used instead of wooden sheathing, then screws will have "to" take the place of the nails E, as can readily be understood by those skilled in the art to which this invention relates. I

The joints A each include a cover cap 35 which extends the full length of the batten or joint formed at the adjacent edges of the roofing are rather springy dueto their formation. They are forced into position against the securing 7 elements upon the tops of the battens, and are sprung into position upon the anchor'cleats. Furthermore, the caps 35 each include side walls j 42 and liadapted'to overlap incontact w th the side walls "and ll! of the cleats: inwardlyand: upwardly extending flanges or Wings 45 and 46 similar to the wings 22 and 23 being provided upon the loweredges or margins of the walls 42 and 43'and adapted to'underlie in contac't with the wings 22 and 23, as shown in Figure 1 of the drawing. It should be noted that the wings 22-23 and 45-46 are undercut; that is, they extend upwardly and inwardly so as to prevent dripping water from climbing to the point of contact of p tions 60 and. are rather loose tp permit ofv expansion of the rdoffconstruction without tearing the roofing material.

From the foregoing description of this invention it is quite apparent that an improved batten joint for sheet roofing has been provided which can be manufactured rather inexpensively,

and which may be assembled accurately andefficiently and also quickly, by means of un-' It is to be noted that all parts.

skilled labor. have their position without guessworkupon the part of the operator, and there are no exposed nails or securing elements.

Various changes'in the shape, size and arrangement of partsmay be made to the form of invention herein shown", and described, without departing from the spirit of the invention or the scope of the following claims.

I claim: V

1. In a joint for sheet roofing the combination of anchor cleats applied upon a battenat the joint of the sheet roof section to hold the upturned sides of sheet roofing against the sides of the batten, said anchor cleats having anchor portions, and a batten cap having'parts engaging said anchor portions,,and spring means yieldably holding said parts in anchored relation with the anchor portions of said cleats.

. 2. In a joint constructionto be located at the batten of sheet roofing the combination of sheet roofing having its sides in upturned relation against said batten, anchor cleats, means securing said anchor cleats at spaced intervals along the batten, and an elongated cover cap detachably secured to said anchor cleats in sprung position with the side portions of said cover engaging against the upturned portions ofthe sheet roofing and forcing the latter into contact with the sides of said batten.

' 3."As an article ofmanufacture, an anchor clip for batten joints'of sheet roofing comprising atop wall, downwardly extending divergent side walls, an inturned anchor wing at the lower margin of each side wall, said anchor wings being upturned in inwardly extending acute angled relation of less than 90 with respect to the planes of the respective sidewalls upon which they are positioned. Y I 1 r '4. As an article of manufacture, a covercap for batten'joints of sheet roofing comprising a top wall, relatively divergent side walls, and anasssxrse 111 I a resilient top wall, side walls, and anchor portions on the lower edges of the side walls, said top wall being concavo-convex in cross section with its concave surface facing upwardly.

6. A batten joint construction for sheet roofing comprising short anchor cleats and an elongated cap for anchoring to said cleats, both the cleats and the cap comprising a top wall, relatively divergent side'wallsextending from the side edges of the top wall, and inturned anchor wings, at the lower margins of each ofJthe side walls sloping upwardly.

L7. In a roof construction the combination of sheathing, a batten attached to the sheathing, =roofingsheets opposite sides of the batten upon said. sheathing with side margins upturned against the sides of the batten, anchor cleats secured to said batten at spaced intervals havchor wings on the lower ends of the side walls ing cap securing portions thereon, and a joint cap 'of elongated construction to spring snap into position upon said anchor cleats and secured-thereto by said anchor'portions of said' cleats and in position to hold the side margins of the roofing sheets against the sides of the batten.
